Pyridaphenthion Chemical Properties,Uses,Production
Description
Pyridaphenthion is a pale yellow solid, mp 54.5–56 ?C, vp 0.00147 mPa (20 ?C). Solubility in water is 100 mg/L (20 ?C). It is very soluble in acetone, methanol, and diethyl ether. Log Kow = 3.2.
Uses
Pyridaphenthion is used to control a wide range of chewing and sucking insects and mites in rice, vegetables, fruit and ornamentals.
Safety Profile
Poison by intraperitoneal route. Moderately toxic by ingestion and skin contact. When heated to decomposition it emits very toxic fumes of SOx, POx, and NOx. Used to control chewing and suckmg insects on rice, fruits, vegetables, and cereals.
Metabolic pathway
Pyridaphentluon is photolytically transformed into the oxon and phenylmaleic hydrazide. In the mouse its metabolism involves oxidative dearylation, oxidative desulfuration to the oxon, de-ethylation and conjugation of phenylmaleic hydrazide produced as the ultimate product of stage I metabolism and is typical of many phosphorothioates. A marked difference between metabolism in mice and rats was shown, with rats excreting no desethylpyridaphenthion and excreting all of the phenyl-maleic hydrazide in an unconjugated form.
Metabolism
More than 70% of the dose administered to rats and mice was excreted within 24 h in the urine. The major metabolites excreted are phenylmaleic hydrazide and desethyl pyridafenthion-oxon. The half-life in soil is 11–24 d.
